HEA lice problem involves tiny, parasitic insects (lice) and their eggs (nits) in hair, causing intense itching from bites, especially around the scalp, ears, and neck, and spreading through close contact. Treatment usually involves medicated shampoos (like permethrin or pyrethrin) or wet-combing with a fine-toothed comb to physically remove them and their nits, with retreatment often needed after 7-10 days to kill newly hatched lice, as they don't spread disease but are highly contagious.
